I took this photo of these two Pre CTA , Chicago Surface Lines vechicles. The bus on the left, is a 1944 White bus. The vechicle on the right is a 1922 electric streetcar. These historic transit vechicles were used by the company known as Chicago Surface Lines, wich was mostly a streetcar operator, but used motor buses on lightly patronized routes. The Chicago Transit Authority was formed in November of 1947, from the amalgamation of the CSL, and the Chicago Rapid Transit Company. In the year of 1952, transit bus operator "Chicago Motor Coach" also joined and became part of the CTA. Both of these two historic transit vechicles are restored and operated for the visiting public.
